I've been using SSH to connect to a IBM i system. They recently upgraded they're operating system to 7.1. Zend Studio was working fine after the upgrade, but then all of sudden stopped working with the following error:

I'm having this issue again. All of a sudden my I'm getting the Failed to connect SSHD on [ip address] and I can't connect to my system. I tried re-starting sshd on the ibm i. I also disconnected and re-connected in Zend Studio, but no luck. NETSTAT *CNN shows that SSH is in listen mode. I'm not sure what else to try??

I know you've already solved this, but this might be useful for others: make sure the qusrwrk subsystem is running. If not, enter this on the command line: STRSBS SBSD(QUSRWRK). Then try restarting sshd. I haven't used Zend Studio with V7R1 yet, but I know this is a prerequisite for V6R1.
